Distributor Ignition (Di)

WARNING: This page is about a different car, the 1995 Ford Aerostar. However, it is still accessible from the selected car via links, so may be relevant.

All engines, except those with distributorless ignition systems, use the DI system (formerly Thick Film Ignition-IV (TFI-IV) system). The DI system components consist of ICM, distributor, CMP (Hall Effect) sensor and "E" core ignition coil. The DI distributor is a gear-driven, die-cast unit. A Hall Effect stator assembly is used to trigger ignition coil. This distributor does not use conventional centrifugal/vacuum advance mechanisms. The ICM is mounted to right inner fenderwell.

Distributor uses a Hall Effect switch mechanism to switch primary voltage and send a Profile Ignition Pick-Up (PIP) signal to PCM. The PCM uses PIP input signal to produce a Spark Output (SPOUT) signal, which is sent to the ICM to trigger coil secondary voltage discharge.
